Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

Front

Solve: 3 + 5 x 2

Back

13 (Multiplication is done before addition).

Front

What operation do you perform first in the expression: 8 - 3 + 2?

Back

Subtraction (8 - 3 = 5, then add 2).

Front

Solve: (4 + 6) ÷ 2

Back

5 (First, add 4 and 6, then divide by 2).

Front

What is the result of 2^3?

Back

8 (2 raised to the power of 3 is 2 x 2 x 2).

Front

Which operation is performed first in the expression: 7 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then add 7).

Front

Solve: 10 - (2 + 3) x 2

Back

0 (First, calculate inside the parentheses, then multiply, and finally subtract).

Front

What is the purpose of parentheses in mathematical expressions?

Back

To indicate which operations should be performed first.

Front

Solve: 5 + 3 x (2 - 1)

Back

8 (First, calculate inside the parentheses, then multiply, and finally add).
